BBC News: Caution urged over use of 'carbon unicorns' to limit warming

"The Intergovernmental Panel on Climate Change will shortly publish a report on how the world might stay below this limit. Early drafts said it would require machines to suck carbon out of the air. The ideas are unrealistic, said one expert, calling them "carbon unicorns"."

AllAfrica: As Climate Risks Rise, Scientists Call for Rules On Solar Engineering

"London — Technologies to reflect some of the sun's rays away from Earth, as a way to cool future runaway climate change, are moving closer to becoming a reality, and rules are needed now to govern them, scientists and other experts said on Monday."

The Maritime Executive: Report: Geoengineering Won't Achieve Paris Accord's Goals

"The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference."

Oschlies, A. (2018): Bewertung von Modellqualität und Unsicherheiten in der Klimamodellierung

Oschlies, A. (2018): Bewertung von Modellqualität und Unsicherheiten in der Klimamodellierung. In: Janich N.; Rhein L. (Hg.): Unsicherheit als Herausforderung für die Wissenschaft: Peter Lang D. DOI: 10.3726/b14379

"The chapter discusses sources of uncertainties in climate models and their possible impacts on the model results. The three criteria “adequacy”, “consistency” and “representativeness” are suggested for a comprehensive assessment of the quality of climate models. The fit to data determines the models representativeness. For many climate variables, such as precipitation, cloudiness and the climate sensitivity, this has not significantly improved from the second-to-last to the last assessment report of the Intergovernmental Panel on Climate Change (IPCC)."

Irvine, Peter J.; et al. (2018): Brief communication. Understanding solar geoengineering's potential to limit sea level rise requires attention from cryosphere experts

Irvine, Peter J.; Keith, David W.; Moore, John (2018): Brief communication. Understanding solar geoengineering's potential to limit sea level rise requires attention from cryosphere experts. In: The Cryosphere 12 (7), S. 2501–2513. DOI: 10.5194/tc-12-2501-2018.

"Here we review the literature on solar geoengineering and the cryosphere and identify the key uncertainties that research could address. Solar geoengineering may be more effective at reducing surface melt than a reduction in greenhouse forcing that produces the same global-average temperature response. Studies of natural analogues and model simulations support this conclusion."

New Strait Times: Uncertainties and implications

"In the final analysis, there should be a global moratorium on large-scale geo-engineering intervention in the world’s climate until everything is in place: rules and regulations to be formulated must be accepted at the global level while sufficient research and pilot experiments must be carried out. A global research pool must also be formed. Recent findings regarding geo-engineering must be transparent and open."

McGill International Review: Geo-engineering and Our Uncertain Future

"It is probable that, in an attempt to counteract the effects of global warming, humanity will deliberately engage in a large-scale manipulation of environmental processes that affect the Earth’s climate. This could well be one of the most consequential events in human history. We can predict with reasonable confidence that some “geo-engineering” scheme to extensively modify environment systems or control climate will be implemented in the coming decades. There are two main reasons for this."

Phys.org: Uncertainties related to climate engineering limit its use in curbing climate change

Media article on Ekholm, Tommi; Korhonen, Hannele (2016). "Climate engineering refers to the systematic, large-scale modification of the environment using various climate intervention techniques. However, a new study by VTT and the Finnish Meteorological Institute suggests that the uncertainties associated with climate engineering are too great for it to provide an alternative to the rapid reduction of greenhouse gas emissions."
